GAS-PRODUCING APPARATUS Application fled Hawk 4, 1907,

To all whom it may concern:

Be it known that I, Hermon N. Wnuans, a citizen of the United States, residing at Providence, in the State of Rhode Island, lave invented a new 'and useful Improvement in Gas-Producing Apparatus for Ext nguishing Fires and other urposes, of which the following is a specification.

The nature of my invention consists in the improved construction of an apparatus in which a jet of sulfuric acid is injected into a stream of water which passes through a chamber containing carbonate or bi-carboriate salts, for the manufacture of carbonic acid gas for various purposes,

, sents the elongated and especially for the purpose of extinguishing fires.

In the accompanying drawings, Figure 1 represents a side view of an apparatus embodying my invention. Fig. 2 represents a vertical axial section of the same.

In the drawings, Figs. 1 and 2, A reprecopper recei ing chamthe closely fitting and firmly secured cover B, the said chamber being adapted to receive the several molded blocks C C C, of carbonate or bi-carbonate salts, which blocks constitute the working charge of the a paratus. At the forward end of the cham er A are placed the perforated baffle-plates D and E, which serveto prevent small fragments of the blocks C C from being carried forward into the contracted tapering passage F, and thus interfering with the proper flow of thesolution through the said passage. To the rear of the chamber A is connected the pipe G, through ber provided with which the water is caused to enter the said chamber. Above the elongated chamberA is placed the horizontally arranged elongated acid chamberH made of lead inorder to resist the action of the contained sulfuric acid. The pipe J is connected with the inlet pipe G at the point a, and enters the said acid chamber H, at its rear and then extends downward to near the bottom of the said chamber, whereb the water flowing through the said pipe will enter the said chamber H at its rear, and at near the bottom of the contained acid.

The pipe K located at the forward end of the chamber H, extends downward to near the bottom of the acid in said chamber, and also extends from the chamber H to the center of the contracted passage F, and terminates in the contracted nozzle L. The chamber H is provided with the upwardly extend- Speeiflcation of Letters Patent.

ing tube M,-through which the acid is sup plied tofill the said chamber, the said tube emg closed by means of the tightly fitting screw-cap Aline of hose '0 is attached to the inlet pipe G, and a line of hose P is also attached to the Wall of the contracted delivering passage F.

In the operation of the apparatus, the receiving chamber A is to be properly charged vwith the molded blocks of carbonate or bicarbonate salts C C C, hereinafter called carbonate, and the chamber H filled with the sulfuric acid I, then upon allowing the water under pressure to enter the inlet pipe G, the said water will pass into the chamber A, and after flowing around the said blocks of carbonate salts and dissolving a portion of the same will pass with rapidity and force through the contracted passage F into the hose pipe P, which leads to the fire. In the meantime a portion 'of the water from the pipe G, has

assed from the said ipe through the pipe J, into the acid in the c sponding quantity of acid has been drawn froin the said chamber through the pipe K, and passed into the escaping carbonate solution,

and upon the entrance of the sulfuric acid into,

1. In an apparatus of the character dep scribed, the combination of the receiving chamber provided with a closely fitting cover, and the inlet pipe for directing the passage of the stream of water into the receiving chamber froma source of water supply under pressure, with the acid chamber having an inlet water pipe connected with the water supply pipe for the receiving chamber, and having an outlet pipe terminating within the cavity of the discharge outlet of the receiving chamber, for delivering the acid to the carbonate solution whichflows from the receiving chamber whereby in the continual operation of the apparatus the contents of the acid chamber w1ll be maintained under suitable water pressure.

2. In an apparatus of the character described, the combination of the receiving chamber provided with a contracted delivering end, and with a closely fitting cover at the opposite end, the inlet pipe for directing the passage of the stream of water into the receiving chamber, with an elongated acid chamber having at one end an Inlet water pipe connected with the water-supply pipe for g the receiving chamber, and with an outlet pipe located at the opposite end of the acid 5 chamber, the said outlet pipe connecting with the discharge outlet of the receiving chamber and terminating at a point centrally of the said outlet, whereby the acid will be delivered centrally of the flowing stream ofthe carbonate solution. 7

3. In an ap aratus of the character described the combination of the elongated horizontally arranged receiving chamber, provided with a contracted delivering end, and with a closely fitting cover at'the opposite end, and the inlet pipe for directing the stream of water into the receiving chamber, with the elongated horizontally arranged acid chamber placed above the receiving chamber and havmg at one end an inlet water pipe connected with the water supply pipe for the receiving chamber and with an outlet-pipe located at the opposite end of the acidchamber, the said outlet pipe connectlnglwith the discharge outlet of the receiving 0 amber.

4. In an apparatus of the character described, the combination of the receiving chamber provided with a closely fitting cover, .and the inlet pipe for directing the passage of a stream of water into the receiving chamber from a source of water supply under ressure, 1

with the acid chamber having an in ct water pipe connected with the water-supply pipe for the receiving chamber, and having an outlet pipe terminating within the cavity ofthe discharge outlet 0 the said receivin chamber and deliverin the acid to the car onate solution which ows from the receiving chamber, whereby in the operation of the apparatus, the contents of both the receivin and acid chambers will be held under suitable water pressure.
